Whats the difference

Can't diff them so have to use something else.

Can use cmp to compare bytes.

Column on the right looks like octal/ascii, so let me try using that.

cmp -l kitters.jpg cattos.jpg | awk '{print $2}'

I pasted those values into a file named array.txt.

I needed to write a bash script to parse and convert that from octal into ascii.

#!/bin/bash

array=("$@")

string=''

for i in "${array[@]}"
do
        string+=$(printf '%b' "\\"$i)
done

echo $string

bash solve.sh $(cat array.txt)
